above the burner and adapted to support a bed or mass of refractory pieces or mgots which will be heated by the flame of the burner and thereby retain additional heat in the furnace.

The annular burner consists of a number ofsegments joined together end to end to form a complete ring, andeach segment has a separate gas supply pipe, whereby one or more segments can be used for heating, according to the temperature desired, andany desired se ment can be readily replaced.

The grate 1s mounted upon the burner and is supported thereby to hold the upper bed of material in proper position relative to the burner.

The invention is illustrated in the accompanying drawings in which Figure 1 is a vertical cross section of the burner and the grate, and the bed of material thereon. F 1g. 2 is a perspective view of the burnerfa part of its central plate being broken away. Fig. 3 is a perspective view of the grate.

Referring specifically to the drawings, it will be seen that the burner consists of a number of segments 6. 'These are hollow,

its ends, on the inner side, each segment has ears 10, which are fastened together by bolts 11, to form the whole burner which may be supported in the fire box of the furnace in any suitable manner. A plate 12 is placed within the burner ring, resting on the ears 10, and serves to close the central part.of the burner, except a narrow air space 13 around the edge. The top of the burner body has beveled corners, with jet openings 1% on each side, and a plain or solid part 15 between the rows of jetopenmgs.

The grate consists of a series of radial arms 16 joined at the inner ends to a ring 17, and connected near the outer ends by a ring 19. This grate may be made in segmental sections if desired. The ring 19 'is so located that when the grate is in place above the burner, said ring will be just above and in line with the plain part of the burner ring. The ring 19 is provided with short legs 19 which rest on plain part of burner ring 15. A plate 20 is rovided, to cover the central opening of t e grate. This grate supports a mass or bed of refractory material 21, which may consist of pieces of fire-brick, metal or the like whichwill act to retain the heat imparted thereto by the flame of'the burner. Each segment of the burner has on the outer side thereof lugs 22, and the grate has depending legs 23 which rest on these lugs and thereby support the grate in position, and also support the bed of material on the grate.

The gas supplied to the various segments may be opened or closed according to the quantity of heat desired, and the constructlon is such that the grate can be readily removed for purposes of repair or other- Wise. The plate 12 in the center of the burner serves to distribute the air or cause the flow thereof to the burner, to afiord the necessary air supply to the flame.

What I claim as new is The combination of a burner comprising a plurality of hollow segments having closed ends and a separate supply pipe to each seg-' ment, said segments being fitted together end to end and having inwardly projecting ears at said ends, fastenings between said ears, a plate resting on said ears and spaced at its edge from the segments, to form a narrow air space between the plate and the burner, and a grate supported above the burner and adapted to support a mass of refractory pieces which will be heated by In testimony whereof, I do siflix my sigvthe flame of the burner, said grate having nature in presence of two witnesses.
